Medical care providers are used to be faced with similar problems when dealing with methicillin-resistant Staphylococcus aureus (MRSA). However, nowadays, eradication regimens offer the possibility to remove MRSA from the skin and mucosa of colonized patients, thus interrupting its further spread to a considerable extent. For ESBL-E, effective eradication regimens are not yet available. The current study therefore aims to assess a new approach to ESBL-E eradication. To avoid administration of the eradication regimen to patients at low risk of subsequent BSI with ESBL-E, the study population will be restricted to immunocompromised high-risk patients.
